(Default lower and upper bounds are 0 and 1.) When the first parameter is a RAND, BETINV yields a bounded random variable. BINOMINV(probability, n, p) returns inverse cumulative values for a binomial random variable.When the first parameter is a RAND, BINOMINV yields a bounded integer random variable between 0 and n, with mean n*p. DISCRINV(randprob, values, probabilities) returns inverse cumulative values for a discrete random variable.When the first parameter is a RAND, DISCRINV returns a discrete random variable with possible values and corresponding probabilities in the given ranges. EXPOINV(probability, mean) returns inverse cumulative values for an exponential random variable.When the first parameter is a RAND, EXPOINV yields a nonnegative random variable (often used for random waiting times).
A generalized-lognormal random variable is a constant plus or minus a lognormal random variable.
